Transforming Volatile Amines into Stable Solid Sorbents via Crosslinking for Direct Air Capture of Carbon Dioxide

Key Points

• The aim is to develop stable solid sorbents from volatile amines to improve carbon dioxide capture.
• Crosslinking volatile amines to increase stability of the sorbents.
• Testing for leaching, oxidative degradation, and overall performance in direct air capture.
• The crosslinked sorbents showed significantly reduced leaching compared to non-crosslinked counterparts.
• Improved resistance to oxidative degradation was observed, enhancing longevity and effectiveness.
• Reduction in corrosivity was evidenced, indicating safer application in carbon capture systems.
